re: uranium prices up us 48.00 lb Great arvo rise....:)

Alliance most have more great results ahead and some very interested new "investors" - Big Boys wanting to be part of this very interesting investment...hehehe

Good accumulation happening.....don't get caught without this one on your list IMHO...because when the "real news" comes out......it will be proper re-rated for sure...

Tomorrow should be a good day across the board for the Australian Market.....BHP should lift our market ? :))))
BHP posts record $13.7bn annual profit
BHP Billiton has posted an Australian record annual net profit of $US10.45 billion ($13.73 billion), and says the global economic outlook continues to be positive. The company's net profit rose 63.4 per cent in the 2005/06 year.

Hey hcraboc,

Great stuff hey ? :))) great technology... :))

A Prompt Fission Neutron (PFN) tool is used to
overcome this disequilibrium, giving a true reading
without the need to drill core holes. The PFN tool was
first developed by Sandia Laboratories and Mobile R
& D for the oil exploration industry in the 1970s.
When the patent expired in 1999, it became available
to the uranium exploration industry, though there are
still only about half a dozen of them being used worldwide
today. They are complex, heavy, difficult and
potentially dangerous to use and they are expensive,
costing about $0.5m each. They tend to be custom
built for the end user. Untroubled by the patent, the
Russians developed a similar tool and called it the
KND System. This has been actively used in ISL
mines in Kazakhstan.
A PFN tool is a down-hole instrument measuring 3m
in length and weighing about 50 kg. Inside is a pulsed
neutron source about the size of a light bulb. High
voltages accelerate deuterium ions into a tritium target
and this produces 14MeV neutrons which are emitted
into the rock to test for uranium. Epithermal neutrons
collide with the country rocks and slow down to form
thermal neutrons. If they find an atom of 235U it causes
slow fission at the atomic level, which produces a
characteristic 2MeV neutron.
Thermal flux and epithermal flux generated by the
fission reaction are read by the PFN tool. The ratio of
epithermal to thermal neutrons is directly proportional
to 235U levels. Only 235U is naturally fissionable in the
natural environment.
Use of the PFN tool and the re-estimation of uranium
grades can result in variations being plus or minus
30% or more when compared with gamma ray log
calculations. So far, at 4 Mile, six holes have been
tested with the PFN tools. It is believed that there has
been no significant downgrading of grades as a result
of the tests.
